Sov

, 9 may be'embodiedfyltwill belnotedwthat `a Y former and driver is shown in Figs. G and Gb. On the base-plate are two guideways. One (marked 16) is to guide the block 7, the functions of which are substantially the same as described 'in connection with the sleeve of right-hand former, and the other, 47, being for receiving and holding the guide and female former 13' 14', similar to the parts 1314, before described. The guide or part is rigidly secured to the base-plate 1 by a screw 48, while female former or part 14' is movable in the Way 47 a certain distance, its movement therein being limited by a piu/19, projecting into the slot. Upon the base-plate 1 is a perforation 51, in which a rod 52, surrounded by a spring 53, slides. The spring 53 acts upon the female former 14 and tends to press the latter into engagement with the guide 13'. Projecting upwardly from the base-plate 1 are standards 54, carrying rods 55, which act as guides for the male former and driver proper in their travel across the base-plate. The

former-bar-cai-r 'ino' block 7 has an extension 5G, carrying pivotally at 20' a lever 59. At the forward part of the carrying-frame is a Spring G0, which tends to normally hold the tongue 61 of the lever 59 in the slot 12. The operation of the left-hand former and driver being similar to that of the right-hand one, a description of such operation is deemed unnecessary.

Referring to Fig. 6, I will give a brief description of the box-hinging machine to indicate clearly the application of my invention thereto. 2G is the frame supportingthe mechanism. In the frame is journaled a pulleywheel 27, to which a constant rotary motion from any convenient source of power is imparted, and from the pulley motion is transmitted to the other parts of the mechanism. 28 is a reel from which the wire 29 for forming the staples is fed to the formers and drivers. 30 and 31 are intermeshing gearwlieels which feed forward the wire 29. 32 is a forked arm to which an intermittent rocking motion is imparted bya pin and roll 33 on the upper end of the casing 10. During the upward movement oi' the driver and former the forked arm is made'to point upwardly, as

shown in Fig. 6and the wire-feed mechanism is held stationary. When the former and driver is moved downwardly, the forked arm is struck by the [pin and roller 33 and by means of'suitable connection with the gearwheels 30 and 31 causes the latter to revolve and feed the wire 29.

Referring to Fig. 7, showing on au enlarged scale the pair of drivers and formers, 3-1 is a link (connected withthe power-supply) havingan arm 35, mounted on a shaft 36. On the shaft 3G are rocking arms 37 and 3S, being pivoted at 39 with links 40, connected to the pins 9 in the lugs S of the former-bar-carrying frames. The link Set has a reciprocating motion, and from it the formers and drivers are alternately operated.

The wire for forming the staple is fed through a hole 41 laterally across the slot 12 at the point where the parts 13 and 14, forming the slot 12, meet.` The proper length of wire for forming a staple is then cut olf by any suitable cutting device, the severed portion of the wire being left Yin the hole 41. This cutting mechanism is substantially the same as that shown in Letters Patent of the United States granted March 26, 1901, No.A

670,816, to D. H. Saunders. The fixed cutter-blade is indicated generally at S in Fig. 6 and the movable cutting-knife at S'. This latter is operated in the same manner as that shown in the patent by a cam projection R5 on the shaft r3 of the forked arm 32. The knife is retracted by a spring S. Vhen the wire is in position, the male driver and former is at the forward part 42 of the slot 12. As the male drivers and formers are drawn backward by the arms 37 and 38 the rear end of the tongue 21 strikes the wire 29, presses it against the end ofthe female former 14, and carries back with it the female former 14E until the latter strikes and is stopped by the pin 16 in the way 3. The female former 14 is made to move back in this way in order that the ends of the piece of wire may be free to bend forward and into the slot 12 in the female former 14 in the form of a staple as the driver is drawn farther backward. Vhen the. staple has thus been completely formed in the slot 12, the j scribed, and itis then driven forward. In the latter movement the notched part 22 of the tongue 21 engages with the staple in the slot IOO IIO

12, and the staple is pushed forward through the @length of the slot and into the box `or other device ready to receive it. The other staple, which shall interlock with the iirst onedriven, as described, so as to form a hinge, is driven by the other of the two drivers and formers illustrated on the boxing-machine shown in the drawings, the operation of which is the same as the operation which I have described in detail.

It will be understood that my invention I claim as new, and 'desire to secure by Letters Patent,'is- L l. In combination the base-plate having a track or way therein containing af female formerhaving a sliding motion, a channel in said female former, in `which the staple is formed, a stationary guide containing a cor` responding channel, means for holding the female former and guide together while the staple is being driven -anda male staple former and driver guided upon said'baseplate, substantially asV described.
